PASSING. “Antennation is involved in many aspects of ant social life such as kin recognition, brood discrimination, and enemy specification whereas licking is a grooming behavior performed by ants on their larvae and other nest mates. The occurrence of a set of distinctive behaviors typical of ant-larvae care, including antennation, transportation to the brood chamber, and licking, along with their high adoption rate, strongly suggests that the flat morph is successfully mimicking ant larvae.”
